Association between vasomotor rhinitis and irritable bowel syndrome.

Allergy Rhinol (Providence) 2016 Jan;7(4):249-255

Department of Biotechnological and Applied Clinical Sciences, University of L'Aquila, L'Aquila, Italy.

Background: Vasomotor rhinitis (VMR) and irritable bowel syndrome (IBS) are two of the most widespread pathologies in industrialized countries, and they have a substantial impact on health-related quality of life.

Objective: To investigate the relationship between VMR and IBS to provide evidence to classify VMR and IBS as a sole disorder.

Methods: The study included 150 patients from San Salvatore Hospital, L'Aquila: 50 with VMR, 50 with IBS, and 50 healthy volunteers.

Results: With regard to a probable link between VMR and IBS, 62 patients of the whole population, 150 patients (41.3%) were affected by both VMR and IBS, 33 subjects (22%) were not affected by VMR or IBS, 25 patients (16.67%) only had VMR, and 30 patients (20%) only had IBS. When considering the 87 subjects affected by VMR, 62 of them also had IBS (71.26%). In turn, when considering all 92 subjects with IBS, 62 (67.39%) had VMR. We found a significant association among IBS and nasal obstruction, rhinorrhea, and turbinates, and among VMR and a change in stool consistency and abdominal pain. Among the patients affected by nonallergic rhinitis (NAR), we found a prevalence of NAR with eosinophils (31%) compared with the other cytologic types.

Conclusion: This study expanded the knowledge of the link between VMR and IBS, also the correlation between typical VMR symptoms and IBS, and about the correlation between typical IBS symptoms and VMR. For future implications, the diagnosis of NAR indicated the need to check for the presence of IBS, by using the Rome III criteria, and a diagnosis of IBS indicated the need to check for the presence of VMR. More studies are needed to find the pathogenetic mechanisms to explain the clinical correlation between VMR and IBS as seen in the present study.

Olfactory Dysfunction, Olfactory Bulb Volume and Alzheimer's Disease: Is There a Correlation? A Pilot Study1.

J Alzheimers Dis 2015 ;48(2):395-402

Department of Applied Clinical Sciences and Biotechnologies, University of L'Aquila, L'Aquila, Italy.

Background: Olfactory dysfunction is present since the earliest stage of Alzheimer's disease (AD). In AD patients, the olfactory impairment has been correlated with atrophy of some structures of the olfactory system, but the role of the olfactory bulb remains unclear.

Objective: The aim of our work is to test if patients suffering from AD exhibit a statistically significant reduction of the average volume of the olfactory bulb (OBV) compared to healthy subjects.

Methods: 78 subjects were enrolled in the study and divided into three groups: 28 healthy elderly (22 females, 6 males, mean age 69.4 ± 9.2), 25 patients with mild cognitive impairment (MCI) amnestic type (14 females, 11 males, mean age 74.5 ± 7.5), and 25 mild AD patients (14 females, 11 males, mean age 73.7 ± 6.8). Every subject underwent an MRI study of the olfactory bulb and an olfactory assessment with the Sniffin' Stick Extended Test.

Results: The statistical analysis showed no correlation between the OBV and MCI or AD. Moreover, olfactory function and OBV were not correlated in any of the three groups.

Conclusion: The reduction of OBV does not seem to represent an index of neuronal damage in the earliest stages of AD.

Inactivation of human salivary glutathione transferase P1-1 by hypothiocyanite: a post-translational control system in search of a role.

PLoS One 2014 13;9(11):e112797. Epub 2014 Nov 13.

Department of Chemical Sciences and Technologies, University of Rome "Tor Vergata", 00133 Rome, Italy.

Glutathione transferases (GSTs) are a superfamily of detoxifying enzymes over-expressed in tumor tissues and tentatively proposed as biomarkers for localizing and monitoring injury of specific tissues. Only scarce and contradictory reports exist about the presence and the level of these enzymes in human saliva. This study shows that GSTP1-1 is the most abundant salivary GST isoenzyme, mainly coming from salivary glands. Surprisingly, its activity is completely obscured by the presence of a strong oxidizing agent in saliva that causes a fast and complete, but reversible, inactivation. Although salivary α-defensins are also able to inhibit the enzyme causing a peculiar half-site inactivation, a number of approaches (mass spectrometry, site directed mutagenesis, chromatographic and spectrophotometric data) indicated that hypothiocyanite is the main salivary inhibitor of GSTP1-1. Cys47 and Cys101, the most reactive sulfhydryls of GSTP1-1, are mainly involved in a redox interaction which leads to the formation of an intra-chain disulfide bridge. A reactivation procedure has been optimized and used to quantify GSTP1-1 in saliva of 30 healthy subjects with results of 42±4 mU/mg-protein. The present study represents a first indication that salivary GSTP1-1 may have a different and hitherto unknown function. In addition it fulfills the basis for future investigations finalized to check the salivary GSTP1-1 as a diagnostic biomarker for diseases.

Clinical management of a patient with advanced mucosal malignant melanoma in the sinonasal area.

Ear Nose Throat J 2014 Jan;93(1):E1-5

Department of Applied Clinical Sciences, University of L'Aquila, Viale S. Salvatore, Edificio 6, Ingresso A, Fraz. Coppito, 67100 L'Aquila, Italy.

We describe a case of mucosal malignant melanoma in the sinonasal area of a 65-year-old woman. She presented with a history of nasal obstruction and epistaxis with subsequent tenderness, facial anesthesia involving cranial nerve V2, red eye, proptosis, diplopia, and conjunctival chemosis. Computed tomography detected a nonspecific solid mass that had involved the left maxillary sinus and surrounding tissues, with extension into the nasal cavity and invasion of the orbital floor and eye muscles. Histopathologic examination of the neoplasm revealed that it was a malignant melanoma. We performed a radical hemimaxillectomy that extended to the orbit, which allowed for radical excision of the tumor. Postoperatively, the patient received adjuvant chemotherapy and radiotherapy. Mucosal melanoma in the head and neck is a rare and highly malignant neoplasm. We suggest that malignant melanoma be suspected when a small-round-cell tumor is found on light microscopy, and we confirm the usefulness of immunohistochemical investigations.

Association between sleep disorders, hyperacusis and tinnitus: evaluation with tinnitus questionnaires.

Noise Health 2013 Mar-Apr;15(63):91-5

Department of Biotechnological and Applied Clinical Sciences, University of L'Aquila, Italy.

Patients with tinnitus are heterogeneous and several factors influence the impact of this symptom on the quality of life. The aim of the study is to evaluate the relationship between age, gender, sleep disorders, hyperacusis and tinnitus annoyance and to demonstrate the utility of tinnitus questionnaires as screening tools for sleep disorders and hyperacusis in patients with tinnitus. 37 consecutive patients (18 males and 19 females) with subjective tinnitus lasting over 3 months were evaluated with a complete interview, otological examination, pure tone audiometry, Italian version of tinnitus sample case history (TSCH) and tinnitus handicap inventory (THI). Statistical analysis was performed with the Wilcoxon's rank sum test, the Spearman's rho non-parametric correlation and the logistic regression analysis. THI grades were slight (16%), mild (32%), moderate (30%), severe (19%) and catastrophic (3%). Based on the answers to TSCH 20 patients reported sleep disorders (54%) and 20 patients reported hyperacusis (54%). 11 patients (30%) reported sleep disorders and hyperacusis. No significant correlation was found between the severity of tinnitus and patients' age and gender. Significant correlation was found between sleep disorders (P = 0.0009) and tinnitus annoyance and between hyperacusis (P = 0.03) and tinnitus annoyance. TSCH and THI may be considered as screening tools in the clinical practice to evidence sleep disorders and hyperacusis in patients with tinnitus.

Olfactory deficit and hippocampal volume loss for early diagnosis of Alzheimer disease: a pilot study.

Alzheimer Dis Assoc Disord 2014 Apr-Jun;28(2):194-7

Departments of *Aging Science †Radiology, Umberto I Hospital, Sapienza, University of Rome, Rome Departments of ‡Applied Sciences, ENT §Applied Sciences, Section of Clinical Epidemiology, University of L'Aquila, L'Aquila, Italy.

Background: The aim of this pilot study was to verify the role of olfactory test and volumetric magnetic resonance imaging measure of hippocampus to predict conversion from mild cognitive impairment to Alzheimer disease (AD).

Materials And Methods: Eighteen patients with amnesic mild cognitive impairment, broadly defined, were followed at 12 months. Hypothesized baseline predictors for follow-up conversion to AD were olfactory deficit and hippocampal volumes loss.

Results: In the 1-year follow-up, 5 patients converted to AD. The 2 clinical predictors olfactory test and hippocampal volume loss showed the same sensitivity of 92.3% but the olfactory test showed a higher specificity than the hippocampal volume loss (75% vs. 60%).

Conclusions: Our findings suggest the potential utility of olfactory test and hippocampal volume loss for early detection of AD.

New trends in tinnitus management.

Open Neurol J 2011 Mar 22;5:12-7. Epub 2011 Mar 22.

Surgical Sciences Department, ENT, University of L'Aquila, L'Aquila, Italy.

Tinnitus is a perception of sound in absence of sound stimulation. Tinnitus in many cases cannot be eliminated by conventional medical treatment with drugs or surgery. Some people who begin to notice tinnitus, whether spontaneous or induced by noise, trauma or other insult, will experience spontaneous resolution, but many patients will have persistent tinnitus. For some of them, tinnitus sensation will be joined by tinnitus suffering, with many adverse effects like anxiety, depression and sleep disorders. For these tinnitus sufferers the psychological and acoustic approach proposed by the Tinnitus Retraining Therapy and Acoustic Desensitization Protocol may be helpful. Periodically new treatments are suggested like low-frequency repetitive transcranial magnetic stimulation and sequential phase shift sound cancellation treatment based on the frequency and loudness matching of the tinnitus. The aim of this work is to review modern considerations for the treatment of tinnitus.

Smell and preclinical Alzheimer disease: study of 29 patients with amnesic mild cognitive impairment.

J Otolaryngol Head Neck Surg 2010 Apr;39(2):175-81

Objectives: To evaluate the olfactory function in patients with amnesic mild cognitive impairment (aMCI) and the relationship to the progression from aMCI to Alzheimer disease (AD).

Design: Cohort prospective study on aMCI patients at the first evaluation (T0) and at the 18-month follow-up (T1).

Setting: Alzheimer Unit of the University of L'Aquila, Italy.

Methods: Twenty-nine aMCI patients were enrolled in this study.

Main Outcome Measures: Olfactory function was studied with the Sniffin' Sticks Screening Test (SSST) and the Sniffin' Sticks Extended Test (SSET). Olfactory functions were related to neurocognitive functions assessed by the Mini-Mental State Examination (MMSE) and the Mental Deterioration Battery (MDB).

Results: At T0, aMCI patients showed an olfactory impairment and all of the aMCI patients had lower olfaction scores at T1. At T1, 9 of the 29 aMCI patients (31%) developed AD and had lower mean SSST and SSET scores than 20 aMCI patients who did not develop AD. The most significant relationship was found between olfactory discrimination and visuospatial ability, language skill, and the Rey Immediate test of the MDB and between olfactory identification and the Rey Delayed test.

Conclusion: Odour discrimination and identification performance correlated more prominently than detection thresholds with performance on neuropsychological tests. We concluded that the olfactory deficit occurs early in aMCI, so we suggest introducing the clinical routine use of the olfactory test for early identification of the progression of the decline from aMCI to AD.
